[elgatollorando]

Good morning.

I don't succed to find aluminium or to build aircrafts, boats. Can somebody help me?

Thank you.

Post scriptum. Ther is one week that I have reinstalled the game and I have forgotten how it functioned. Thank you for your understanding.

If it can reassure you, I speak fluenter Spanish but it can't resolve the communication problem.

I'll assume that:

A. You have the required tech (Rocketry, IIRC)
B. You are not playing a scenario or a mod (in this case, you may want to check the scenario rules again, maybe it doesn't have alluminum)

Then, it's just bad luck and about the only thing you can do is see which one of neighbours has it, and either trade for it, or go to war and take it.

Once again, you need to have Rocketry and make sure you haven't changed any rules.

If you're playing a scenario, you can load it in the editor and see if it actually has any.

There have been instances where no resource of a certain shows up at all.
It's very rare but it does happen, I've seen it once with IIRC aluminum.
It can happen when only a few of the needed sort of tiles are availlable. So it will happen more on small maps with extreme conditions.
